Specification of Letters Patent.

rammed June so, rare.

Application filed December 20, 1912. Serial No. 737,799.

To all whom it may concern Be it known that I, FREDERio PARKER, ofBedford, in the county of Middlescx and State of Massachusetts, acitizen of the United States, have invented a new and useful Improvementin Window-Shields, of which the following is a specification.

My invention relates to means adapted to shield a window fro-1n thesounds arising from a noisy street. A shield adapted for this purposehas heretofore been constructed and successfully used.

My present form of shield while constructed on the same scientificprinciple, viz: that of reflecting sound without materially excludinglight, is simple in construction, easy to adjust and keep clean and maybe used also as fire shutters for the window to which it is applied.

My invention will be understood by reference to the drawings, in whichFigure 1 is an elevation of a window to which my shield has been appliedin its preferred form, the shield being out of use. Fig. 2 is ahorizontal section taken near the top of the window showing the shieldin use. Fig. 3 is a top view showing my invention used as fire shutters,and Fig. 4 is a vertical section through the middle of the windowshowing one of the shutters in elevation.

A. are the sashes of the window, A being the sill, A being the windowledge, and A the outer wall of the building. Themain part of the windowshield comprises two members B and B in the nature of shutters eachconstructed in the form of my invention shown of a metal frame 6 havinga suitable crossbar b dividing it into two parts, this frame holding twoplates 6 and preferably made of wire glass or other similar transparentmaterial of such character as not to be affected by ordinary fireexposure. Each one of these members is provided with hinges b 6 by whichit may be hinged to the side of the window.

In the preferred form of my invention each member is wider than half thewidth of the window so that when bowed or so closed together as to bringtheir outer edges in contact with each other they will form an angularinclosure or ventilating passage B (see Fig. 2 whereeach member is shownat approximately an angle of forty-five degrees with the vertical planeof the wall of the building, the two outer edges of the members being incontact.) When the window is open they deflect waves of sound fromentering the window so as to reduce materially the noise which wouldotherwise enter the room. In addition as shown each member carries anextension C, C preferably hinged to its lower edge and shaped to closein the bottom of the passage B so that the opening thereto is only atthe top. These extensions C, C are preferably hinged each to its ownmember B, B in such a manner that when raised into vertical position asshown in Fig. 1 they will lie within the projection formed by the frame6, b 22 In practice these members B, B may be thrown out of use in whichcase they may be looked back against the outer wall of the building A byany suitable fastener a, as shown in Fig. 1, or the members may be bowedas shown in Fig. 2 in which case the extensions C, C are dropped'intohorizontal position, one extension carrying a hook c and the other aneye 0 so that they may be locked in place, these extensions in this caseresting upon the window ledge A It will be noted in Figs. 1 and 3 thatone member B has a hook b on its upper edge and the other an eye I).When these members are bowed as above described the hook b and eye 6above referred to are caused to engage, thus holding the membersthemselves in place. In addition these members may be used as fireshutters, that is, they may be closed over the window at night asbecause of their relative width they will overlap. The hinges b for onemember are mounted on an offset 6 of a thickness substantially equal tothe thickness of the other member and when the two are shut togetherover a window (see Fig. 3) they may be held closed by means of aturn-button or in some other convenient way. The turnbutton which Iprefer is shown in Fig. 3 and comprises a spindle (Z passing through oneof the members and having on the inner end a handle al by which it maybe turned and on the outer end a finger (Z which when turned into theposition shown in Fig. 8 overlaps the overlapping member and holds thetwo members closed against the window frame.

In case of fire where it is necessary to enter the window, it is asimple matter to turn'the finger (Z to release the members B so that theshutters may be opened from the outside. Under ordinary conditions themembers may be locked in this way at night and hence provide ample 'fireprotection'to the building inside.

It will beclear to any one skilled in the art that my invention may beotherwise applied. In its preferred form it consists primarily inshutters or shield members each wider than half the window so that whenthe ends are brought together they Will abut, leaving a. passage suchasB these members being constructed preferably of Wire glass wherebythey will be transparent or at least translucent, thus reducing butlittle the amount of light which gets into the shown that a'largeportion of the sound wavesrising from a street may be sufficientlydeflected by such to enable a room to'be used comfortably for purposesof dictation, telephoning, conferences or other such purposes while thewindow is open even when the room is upon a very nolsy street.

I do not mean 'to limit myself to shutters proportioned exactly as shownor to a pair of shutters, each being made in one piece, nor to shutterswhich are transparent or translucent, my purpose being to provide aclosure which shall be sufiiciently long or so shaped or jointed as toenable it to form with the window a chamber of suiiicient size to giveplenty of fresh air to the room when the window is open and at the sametime to present to the sound waves an obstruction which shall deflectthem from their direct course into the room.

l/Vhat I claim as my invention is:-

In combination with a window frame, two members each wider than one halfthe width of the window frame, one hinged at each lateral. edge of saidframe and each having a floor member hinged to it, means for looking theouter edges of said first-named members together in bowed relation, andmeans for supporting said floor members in horizontal position to closethe passage between said first-named members and said window frame.
